CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority under 35 U.S.C. §§ 119 and 365 to Korean Patent Application No. 10-2016-0153147, filed in the Korean Intellectual Property Office on Nov. 17, 2016, the disclosure of which is incorporated herein by reference.

BACKGROUND Field

The present invention relates to a mobile terminal and, more particularly, to registration of information on an application, which is being executed on a watch type terminal, on a screen of a mobile terminal.

Discussion of Background

Terminals may be generally classified as mobile/portable terminals or stationary terminals according to their mobility. Mobile terminals may also be classified as handheld terminals or vehicle mounted terminals.

Mobile terminals have become increasingly more functional. Examples of such functions include data and voice communications, capturing images and video via a camera, recording audio, playing music files via a speaker system, and displaying images and video on a display. Some mobile terminals include additional functionality which supports game playing, while other terminals are configured as multimedia players. More recently, mobile terminals have been configured to receive broadcast and multicast signals which permit viewing of content such as videos and television programs.

As such functions become more diversified, the mobile terminal can support more complicated functions such as capturing images or video, reproducing music or video files, playing games, receiving broadcast signals, and the like. By comprehensively and collectively implementing such functions, the mobile terminal can be embodied in the form of a multimedia player or device.

Efforts are ongoing to support and increase the functionality of mobile terminals. Such efforts include software and hardware improvements, as well as changes and improvements in the structural components.

SUMMARY

Accordingly, an object of the present invention is to address problems with the related art.

An object of the present invention is to provide a mobile terminal capable of rapidly executing an application, which is being executed by a watch type mobile terminal.

A mobile terminal includes a display unit, a short-range communication module configured to perform short-range communication with a watch type mobile terminal and a controller configured to control the display unit and the short-range communication module. The controller receives information on an application executed by the watch type mobile terminal and displays an application icon of the application on a wallpaper of the mobile terminal based on the received information on the application.

According to various embodiments of the present invention, a user can receive more information than information on a screen displayed by a watch type mobile terminal through a mobile terminal.

The input unit 120 includes a camera 121 for obtaining images or video, a microphone 122, which is one type of audio input device for inputting an audio signal, and a user input unit 123 (for example, a touch key, a push key, a mechanical key, a soft key, and the like) for allowing a user to input information. Data (for example, audio, video, image, and the like) is obtained by the input unit 120 and can be analyzed and processed by controller 180 according to device parameters, user commands, and combinations thereof.

The sensing unit 140 is typically implemented using one or more sensors configured to sense internal information of the mobile terminal, the surrounding environment of the mobile terminal, user information, and the like. For example, in FIG. 1A, the sensing unit 140 is shown having a proximity sensor 141 and an illumination sensor 142.

The mobile terminal 100 can be configured to utilize information obtained from sensing unit 140, and in particular, information obtained from one or more sensors of the sensing unit 140, and combinations thereof.

The output unit 150 is typically configured to output various types of information, such as audio, video, tactile output, and the like. The output unit 150 is shown having a display unit 151, an audio output module 152, a haptic module 153, and an optical output module 154.

The display unit 151 may have an inter-layered structure or an integrated structure with a touch sensor in order to facilitate a touch screen. The touch screen can provide an output interface between the mobile terminal 100 and a user, as well as function as the user input unit 123 which provides an input interface between the mobile terminal 100 and the user.

The interface unit 160 serves as an interface with various types of external devices that can be coupled to the mobile terminal 100. The interface unit 160, for example, can include any of wired or wireless ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, and the like. In some cases, the mobile terminal 100 can perform assorted control functions associated with a connected external device, in response to the external device being connected to the interface unit 160.

The memory 170 is typically implemented to store data to support various functions or features of the mobile terminal 100. For instance, the memory 170 can be configured to store application programs executed in the mobile terminal 100, data or instructions for operations of the mobile terminal 100, and the like. Some of these application programs can be downloaded from an external server via wireless communication. Other application programs can be installed within the mobile terminal 100 at time of manufacturing or shipping, which is typically the case for basic functions of the mobile terminal 100 (for example, receiving a call, placing a call, receiving a message, sending a message, and the like). It is common for application programs to be stored in the memory 170, installed in the mobile terminal 100, and executed by the controller 180 to perform an operation (or function) for the mobile terminal 100.

The controller 180 typically functions to control overall operation of the mobile terminal 100, in addition to the operations associated with the application programs. The controller 180 can provide or process information or functions appropriate for a user by processing signals, data, information and the like, which are input or output by the various components depicted in FIG. 1A, or activating application programs stored in the memory 170. As one example, the controller 180 controls some or all of the components illustrated in FIGS. 1A-1C according to the execution of an application program that have been stored in the memory 170.

The power supply unit 190 can be configured to receive external power or provide internal power in order to supply appropriate power required for operating elements and components included in the mobile terminal 100. The power supply unit 190 can include a battery, and the battery can be configured to be embedded in the terminal body, or configured to be detachable from the terminal body.

Referring still to FIG. 1A, various components depicted in this figure will now be described in more detail. Regarding the wireless communication unit 110, the broadcast receiving module 111 is typically configured to receive a broadcast signal and/or broadcast associated information from an external broadcast managing entity via a broadcast channel. The broadcast channel may include a satellite channel, a terrestrial channel, or both. In some embodiments, two or more broadcast receiving modules 111 may be utilized to facilitate simultaneously receiving of two or more broadcast channels, or to support switching among broadcast channels.

The broadcast managing entity may be a server which generates and transmits a broadcast signal and/or broadcast associated information, or a server which receives a pre-generated broadcast signal and/or broadcast associated information, and sends such items to the mobile terminal.

The broadcast signal may be implemented using any of a TV broadcast signal, a radio broadcast signal, a data broadcast signal, and combinations thereof, among others. The broadcast signal in some cases may further include a data broadcast signal combined with a TV or radio broadcast signal.

The broadcast signal may be encoded according to any of a variety of technical standards or broadcasting methods (for example, International Organization for Standardization (ISO), International Electrotechnical Commission (IEC), Digital Video Broadcast (DVB), Advanced Television Systems Committee (ATSC), and the like) for transmission and reception of digital broadcast signals. The broadcast receiving module 111 can receive the digital broadcast signals using a method appropriate for the transmission method utilized.

Examples of broadcast associated information may include information associated with a broadcast channel, a broadcast program, a broadcast event, a broadcast service provider, or the like. The broadcast associated information may also be provided via a mobile communication network, and in this instance, received by the mobile communication module 112.

The broadcast associated information can be implemented in various formats. For instance, broadcast associated information can include an Electronic Program Guide (EPG) of Digital Multimedia Broadcasting (DMB), an Electronic Service Guide (ESG) of Digital Video Broadcast-Handheld (DVB-H), and the like. Broadcast signals and/or broadcast associated information received via the broadcast receiving module 111 can be stored in a suitable device, such as a memory 170.

The mobile communication module 112 can transmit and/or receive wireless signals to and from one or more network entities. Typical examples of a network entity include a base station, an external mobile terminal, a server, and the like. Such network entities form part of a mobile communication network, which is constructed according to technical standards or communication methods for mobile communications (for example, Global System for Mobile Communication (GSM), Code Division Multi Access (CDMA), CDMA2000 (Code Division Multi Access 2000), EV-DO (Enhanced Voice-Data Optimized or Enhanced Voice-Data Only), Wideband CDMA (WCDMA), High Speed Downlink Packet access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like). Examples of wireless signals transmitted and/or received via the mobile communication module 112 include audio call signals, video (telephony) call signals, or various formats of data to support communication of text and multimedia messages.

The wireless Internet module 113 is configured to facilitate wireless Internet access. This module may be internally or externally coupled to the mobile terminal 100. The wireless Internet module 113 may transmit and/or receive wireless signals via communication networks according to wireless Internet technologies.

Examples of such wireless Internet access include Wireless LAN (WLAN), Wireless Fidelity (Wi-Fi), Wi-Fi Direct, Digital Living Network Alliance (DLNA), Wireless Broadband (WiBro), Worldwide Interoperability for Microwave Access (WiMAX), High Speed Downlink Packet Access (HSDPA), HSUPA (High Speed Uplink Packet Access), Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced), and the like. The wireless Internet module 113 can transmit/receive data according to one or more of such wireless Internet technologies, and other Internet technologies as well.

In some embodiments, when the wireless Internet access is implemented according to, for example, WiBro, HSDPA, HSUPA, GSM, CDMA, WCDMA, LTE, LTE-A and the like, as part of a mobile communication network, the wireless Internet module 113 performs such wireless Internet access. As such, the Internet module 113 can cooperate with, or function as, the mobile communication module 112.

The short-range communication module 114 is configured to facilitate short-range communications. Suitable technologies for implementing such short-range communications include BLUETOOTH™, Radio Frequency IDentification (RFID), Infrared Data Association (IrDA), Ultra-WideBand (UWB), ZigBee, Near Field Communication (NFC), Wireless-Fidelity (Wi-Fi), Wi-Fi Direct, Wireless USB (Wireless Universal Serial Bus), and the like. The short-range communication module 114 in general supports wireless communications between the mobile terminal 100 and a wireless communication system, communications between the mobile terminal 100 and another mobile terminal 100, or communications between the mobile terminal and a network where another mobile terminal 100 (or an external server) is located, via wireless area networks. One example of the wireless area networks is a wireless personal area networks.

In some embodiments, another mobile terminal (which may be configured similarly to mobile terminal 100) may be a wearable device, for example, a smart watch, a smart glass or a head mounted display (HMD), which can exchange data with the mobile terminal 100 (or otherwise cooperate with the mobile terminal 100). The short-range communication module 114 can sense or recognize the wearable device, and permit communication between the wearable device and the mobile terminal 100. In addition, when the sensed wearable device is a device which is authenticated to communicate with the mobile terminal 100, the controller 180, for example, can cause transmission of data processed in the mobile terminal 100 to the wearable device via the short-range communication module 114. Hence, a user of the wearable device can use the data processed in the mobile terminal 100 on the wearable device. For example, when a call is received in the mobile terminal 100, the user can answer the call using the wearable device. Also, when a message is received in the mobile terminal 100, the user can check the received message using the wearable device.

The location information module 115 is generally configured to detect, calculate, derive or otherwise identify a position of the mobile terminal. As an example, the location information module 115 includes a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal.

As one example, when the mobile terminal uses a GPS module, a position of the mobile terminal can be acquired using a signal sent from a GPS satellite. As another example, when the mobile terminal uses the Wi-Fi module, a position of the mobile terminal can be acquired based on information related to a wireless access point (AP) which transmits or receives a wireless signal to or from the Wi-Fi module.

The input unit 120 can be configured to permit various types of input to the mobile terminal 120. Examples of such input include audio, image, video, data, and user input. Image and video input is often obtained using one or more cameras 121. Such cameras 121 can process image frames of still pictures or video obtained by image sensors in a video or image capture mode. The processed image frames can be displayed on the display unit 151 or stored in memory 170. In some cases, the cameras 121 may be arranged in a matrix configuration to permit a plurality of images having various angles or focal points to be input to the mobile terminal 100. As another example, the cameras 121 can be located in a stereoscopic arrangement to acquire left and right images for implementing a stereoscopic image.

The microphone 122 is generally implemented to permit audio input to the mobile terminal 100. The audio input can be processed in various manners according to a function being executed in the mobile terminal 100. If desired, the microphone 122 can include assorted noise removing algorithms to remove unwanted noise generated in the course of receiving the external audio.

The user input unit 123 is a component that permits input by a user. Such user input can enable the controller 180 to control operation of the mobile terminal 100. The user input unit 123 can include one or more of a mechanical input element (for example, a key, a button located on a front and/or rear surface or a side surface of the mobile terminal 100, a dome switch, a jog wheel, a jog switch, and the like), or a touch-sensitive input, among others. As one example, the touch-sensitive input can be a virtual key or a soft key, which is displayed on a touch screen through software processing, or a touch key which is located on the mobile terminal at a location that is other than the touch screen. Further, the virtual key or the visual key can be displayed on the touch screen in various shapes, for example, graphic, text, icon, video, or a combination thereof.

The sensing unit 140 is generally configured to sense one or more of internal information of the mobile terminal, surrounding environment information of the mobile terminal, user information, or the like. The controller 180 generally cooperates with the sending unit 140 to control operation of the mobile terminal 100 or execute data processing, a function or an operation associated with an application program installed in the mobile terminal based on the sensing provided by the sensing unit 140. The sensing unit 140 can be implemented using any of a variety of sensors, some of which will now be described in more detail.

The proximity sensor 141 can include a sensor to sense presence or absence of an object approaching a surface, or an object located near a surface, by using an electromagnetic field, infrared rays, or the like without a mechanical contact. The proximity sensor 141 can be arranged at an inner region of the mobile terminal covered by the touch screen, or near the touch screen.

The proximity sensor 141, for example, can include any of a transmissive type photoelectric sensor, a direct reflective type photoelectric sensor, a mirror reflective type photoelectric sensor, a high-frequency oscillation proximity sensor, a capacitance type proximity sensor, a magnetic type proximity sensor, an infrared rays proximity sensor, and the like. When the touch screen is implemented as a capacitance type, the proximity sensor 141 can sense proximity of a pointer relative to the touch screen by changes of an electromagnetic field, which is responsive to an approach of an object with conductivity. In this instance, the touch screen (touch sensor) can also be categorized as a proximity sensor.

The term “proximity touch” will often be referred to herein to denote the scenario in which a pointer is positioned to be proximate to the touch screen without contacting the touch screen. The term “contact touch” will often be referred to herein to denote the scenario in which a pointer makes physical contact with the touch screen. For the position corresponding to the proximity touch of the pointer relative to the touch screen, such position will correspond to a position where the pointer is perpendicular to the touch screen. The proximity sensor 141 can sense proximity touch, and proximity touch patterns (for example, distance, direction, speed, time, position, moving status, and the like).

In general, controller 180 processes data corresponding to proximity touches and proximity touch patterns sensed by the proximity sensor 141, and cause output of visual information on the touch screen. In addition, the controller 180 can control the mobile terminal 100 to execute different operations or process different data according to whether a touch with respect to a point on the touch screen is either a proximity touch or a contact touch.

A touch sensor can sense a touch applied to the touch screen, such as display unit 151, using any of a variety of touch methods. Examples of such touch methods include a resistive type, a capacitive type, an infrared type, and a magnetic field type, among others.

As one example, the touch sensor can be configured to convert changes of pressure applied to a specific part of the display unit 151, or convert capacitance occurring at a specific part of the display unit 151, into electric input signals. The touch sensor can also be configured to sense not only a touched position and a touched area, but also touch pressure and/or touch capacitance. A touch object is generally used to apply a touch input to the touch sensor. Examples of typical touch objects include a finger, a touch pen, a stylus pen, a pointer, or the like.

When a touch input is sensed by a touch sensor, corresponding signals can be transmitted to a touch controller. The touch controller can process the received signals, and then transmit corresponding data to the controller 180. Accordingly, the controller 180 can sense which region of the display unit 151 has been touched. Here, the touch controller can be a component separate from the controller 180, the controller 180, and combinations thereof.

In some embodiments, the controller 180 can execute the same or different controls according to a type of touch object that touches the touch screen or a touch key provided in addition to the touch screen. Whether to execute the same or different control according to the object which provides a touch input can be decided based on a current operating state of the mobile terminal 100 or a currently executed application program, for example.

The touch sensor and the proximity sensor can be implemented individually, or in combination, to sense various types of touches. Such touches includes a short (or tap) touch, a long touch, a multi-touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.

If desired, an ultrasonic sensor can be implemented to recognize position information relating to a touch object using ultrasonic waves. The controller 180, for example, can calculate a position of a wave generation source based on information sensed by an illumination sensor and a plurality of ultrasonic sensors. Since light is much faster than ultrasonic waves, the time for which the light reaches the optical sensor is much shorter than the time for which the ultrasonic wave reaches the ultrasonic sensor. The position of the wave generation source can be calculated using this fact. For instance, the position of the wave generation source can be calculated using the time difference from the time that the ultrasonic wave reaches the sensor based on the light as a reference signal.

The camera 121 typically includes at least one a camera sensor (CCD, CMOS etc.), a photo sensor (or image sensors), and a laser sensor. Implementing the camera 121 with a laser sensor can allow detection of a touch of a physical object with respect to a 3D stereoscopic image. The photo sensor can be laminated on, or overlapped with, the display device. The photo sensor can be configured to scan movement of the physical object in proximity to the touch screen. In more detail, the photo sensor may include photo diodes and transistors at rows and columns to scan content received at the photo sensor using an electrical signal which changes according to the quantity of applied light. Namely, the photo sensor can calculate the coordinates of the physical object according to variation of light to thus obtain position information of the physical object.

The display unit 151 is generally configured to output information processed in the mobile terminal 100. For example, the display unit 151 can display execution screen information of an application program executing at the mobile terminal 100 or user interface (UI) and graphic user interface (GUI) information in response to the execution screen information.

In some embodiments, the display unit 151 may be implemented as a stereoscopic display unit for displaying stereoscopic images. A typical stereoscopic display unit can employ a stereoscopic display scheme such as a stereoscopic scheme (a glass scheme), an auto-stereoscopic scheme (glassless scheme), a projection scheme (holographic scheme), or the like.

In general, a 3D stereoscopic image includes a left image (e.g., a left eye image) and a right image (e.g., a right eye image). According to how left and right images are combined into a 3D stereoscopic image, a 3D stereoscopic imaging method can be divided into a top-down method in which left and right images are located up and down in a frame, an L-to-R (left-to-right or side by side) method in which left and right images are located left and right in a frame, a checker board method in which fragments of left and right images are located in a tile form, an interlaced method in which left and right images are alternately located by columns or rows, and a time sequential (or frame by frame) method in which left and right images are alternately displayed on a time basis.

Also, as for a 3D thumbnail image, a left image thumbnail and a right image thumbnail can be generated from a left image and a right image of an original image frame, respectively, and then combined to generate a single 3D thumbnail image. In general, the term “thumbnail” can be used to refer to a reduced image or a reduced still image. A generated left image thumbnail and right image thumbnail can be displayed with a horizontal distance difference there between by a depth corresponding to the disparity between the left image and the right image on the screen, thereby providing a stereoscopic space sense.

A left image and a right image required for implementing a 3D stereoscopic image can be displayed on the stereoscopic display unit using a stereoscopic processing unit. The stereoscopic processing unit can receive the 3D image and extract the left image and the right image, or can receive the 2D image and change it into a left image and a right image.

The audio output module 152 is generally configured to output audio data. Such audio data can be obtained from any of a number of different sources, such that the audio data can be received from the wireless communication unit 110 or can have been stored in the memory 170. The audio data can be output during modes such as a signal reception mode, a call mode, a record mode, a voice recognition mode, a broadcast reception mode, and the like. The audio output module 152 can provide audible output related to a particular function (e.g., a call signal reception sound, a message reception sound, etc.) performed by the mobile terminal 100. The audio output module 152 can also be implemented as a receiver, a speaker, a buzzer, or the like.

A haptic module 153 can be configured to generate various tactile effects that a user feels, perceive, or otherwise experience. A typical example of a tactile effect generated by the haptic module 153 is vibration. The strength, pattern and the like of the vibration generated by the haptic module 153 can be controlled by user selection or setting by the controller. For example, the haptic module 153 can output different vibrations in a combining manner or a sequential manner.

Besides vibration, the haptic module 153 can generate various other tactile effects, including an effect by stimulation such as a pin arrangement vertically moving to contact skin, a spray force or suction force of air through a jet orifice or a suction opening, a touch to the skin, a contact of an electrode, electrostatic force, an effect by reproducing the sense of cold and warmth using an element that can absorb or generate heat, and the like.

The haptic module 153 can also be implemented to allow the user to feel a tactile effect through a muscle sensation such as the user's fingers or arm, as well as transferring the tactile effect through direct contact. Two or more haptic modules 153 can be provided according to the particular configuration of the mobile terminal 100.

An optical output module 154 can output a signal for indicating an event generation using light of a light source. Examples of events generated in the mobile terminal 100 can include message reception, call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like.

A signal output by the optical output module 154 can be implemented so the mobile terminal emits monochromatic light or light with a plurality of colors. The signal output can be terminated as the mobile terminal senses that a user has checked the generated event, for example.

The interface unit 160 serves as an interface for external devices to be connected with the mobile terminal 100. For example, the interface unit 160 can receive data transmitted from an external device, receive power to transfer to elements and components within the mobile terminal 100, or transmit internal data of the mobile terminal 100 to such external device. The interface unit 160 can include wired or wireless headset ports, external power supply ports, wired or wireless data ports, memory card ports, ports for connecting a device having an identification module, audio input/output (I/O) ports, video I/O ports, earphone ports, or the like.

The identification module can be a chip that stores various information for authenticating authority of using the mobile terminal 100 and can include a user identity module (UIM), a subscriber identity module (SIM), a universal subscriber identity module (USIM), and the like. In addition, the device having the identification module (also referred to herein as an “identifying device”) can take the form of a smart card. Accordingly, the identifying device can be connected with the terminal 100 via the interface unit 160.

When the mobile terminal 100 is connected with an external cradle, the interface unit 160 can serve as a passage to allow power from the cradle to be supplied to the mobile terminal 100 or can serve as a passage to allow various command signals input by the user from the cradle to be transferred to the mobile terminal there through. Various command signals or power input from the cradle can operate as signals for recognizing that the mobile terminal is properly mounted on the cradle.

The memory 170 can store programs to support operations of the controller 180 and store input/output data (for example, phonebook, messages, still images, videos, etc.). The memory 170 can store data related to various patterns of vibrations and audio which are output in response to touch inputs on the touch screen.

The memory 170 may include one or more types of storage mediums including a Flash memory, a hard disk, a solid state disk, a silicon disk, a multimedia card micro type, a card-type memory (e.g., SD or DX memory, etc.), a Random Access Memory (RAM), a Static Random Access Memory (SRAM), a Read-Only Memory (ROM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Programmable Read-Only memory (PROM), a magnetic memory, a magnetic disk, an optical disk, and the like. The mobile terminal 100 can also be operated in relation to a network storage device that performs the storage function of the memory 170 over a network, such as the Internet.

The controller 180 typically controls the general operations of the mobile terminal 100. For example, the controller 180 can set or release a lock state for restricting a user from inputting a control command with respect to applications when a status of the mobile terminal meets a preset condition.

The controller 180 can also perform the controlling and processing associated with voice calls, data communications, video calls, and the like, or perform pattern recognition processing to recognize a handwriting input or a picture drawing input performed on the touch screen as characters or images, respectively. In addition, the controller 180 can control one or a combination of those components in order to implement various exemplary embodiments disclosed herein.

The power supply unit 190 receives external power or provide internal power and supply the appropriate power required for operating respective elements and components included in the mobile terminal 100. The power supply unit 190 can include a battery, which is typically rechargeable or be detachably coupled to the terminal body for charging.

The power supply unit 190 may include a connection port. The connection port can be configured as one example of the interface unit 160 to which an external charger for supplying power to recharge the battery is electrically connected.

As another example, the power supply unit 190 can be configured to recharge the battery in a wireless manner without use of the connection port. In this example, the power supply unit 190 can receive power, transferred from an external wireless power transmitter, using at least one of an inductive coupling method which is based on magnetic induction or a magnetic resonance coupling method which is based on electromagnetic resonance. Various embodiments described herein can be implemented in a computer-readable medium, a machine-readable medium, or similar medium using, for example, software, hardware, or any combination thereof.

Referring now to FIGS. 1B and 1C, the mobile terminal 100 is described with reference to a bar-type terminal body. However, the mobile terminal 100 can alternatively be implemented in any of a variety of different configurations. Examples of such configurations include watch-type, clip-type, glasses-type, or as a folder-type, flip-type, slide-type, swing-type, and swivel-type in which two and more bodies are combined with each other in a relatively movable manner, and combinations thereof. Discussion herein will often relate to a particular type of mobile terminal (for example, bar-type, watch-type, glasses-type, and the like). However, such teachings with regard to a particular type of mobile terminal will generally apply to other types of mobile terminals as well.

The mobile terminal 100 will generally include a case (for example, frame, housing, cover, and the like) forming the appearance of the terminal. In this embodiment, the case is formed using a front case 101 and a rear case 102. Various electronic components are incorporated into a space formed between the front case 101 and the rear case 102. At least one middle case can be additionally positioned between the front case 101 and the rear case 102.

The display unit 151 is shown located on the front side of the terminal body to output information. As illustrated, a window 151 a of the display unit 151 can be mounted to the front case 101 to form the front surface of the terminal body together with the front case 101.

In some embodiments, electronic components may also be mounted to the rear case 102. Examples of such electronic components include a detachable battery 191, an identification module, a memory card, and the like. Rear cover 103 is shown covering the electronic components, and this cover may be detachably coupled to the rear case 102. Therefore, when the rear cover 103 is detached from the rear case 102, the electronic components mounted to the rear case 102 are externally exposed.

As illustrated, when the rear cover 103 is coupled to the rear case 102, a side surface of the rear case 102 is partially exposed. In some cases, upon the coupling, the rear case 102 may also be completely shielded by the rear cover 103. In some embodiments, the rear cover 103 may include an opening for externally exposing a camera 121 b or an audio output module 152 b.

The cases 101, 102, 103 can be formed by injection-molding synthetic resin or may be formed of a metal, for example, stainless steel (STS), aluminum (Al), titanium (Ti), or the like. As an alternative to the example in which the plurality of cases form an inner space for accommodating components, the mobile terminal 100 can be configured such that one case forms the inner space. In this example, a mobile terminal 100 having a uni-body is formed so synthetic resin or metal extends from a side surface to a rear surface.

If desired, the mobile terminal 100 may include a waterproofing unit for preventing introduction of water into the terminal body. For example, the waterproofing unit may include a waterproofing member which is located between the window 151 a and the front case 101, between the front case 101 and the rear case 102, or between the rear case 102 and the rear cover 103, to hermetically seal an inner space when those cases are coupled.

The mobile terminal includes a display unit 151, a first and a second audio output modules 151 a/151 b, a proximity sensor 141, an illumination sensor 142, an optical output module 154, a first and a second cameras 121 a/121 b, a first and a second manipulation units 123 a/123 b, a microphone 122, interface unit 160 and the like.

It will be described for the mobile terminal as shown in FIGS. 1B and 1C. The display unit 151, the first audio output module 151 a, the proximity sensor 141, an illumination sensor 142, the optical output module 154, the first camera 121 a and the first manipulation unit 123 a are arranged in front surface of the terminal body, the second manipulation unit 123 b, the microphone 122 and interface unit 160 are arranged in side surface of the terminal body, and the second audio output modules 151 b and the second camera 121 b are arranged in rear surface of the terminal body.

However, alternative arrangements are possible and within the teachings of the instant disclosure. Some components can be omitted or rearranged. For example, the first manipulation unit 123 a can be located on another surface of the terminal body, and the second audio output module 152 b can be located on the side surface of the terminal body.

The display unit 151 outputs information processed in the mobile terminal 100. The display unit 151 can be implemented using one or more suitable display devices. Examples of such suitable display devices include a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light emitting diode (OLED), a flexible display, a 3-dimensional (3D) display, an e-ink display, and combinations thereof.

The display unit 151 can be implemented using two display devices, which can implement the same or different display technology. For instance, a plurality of the display units 151 can be arranged on one side, either spaced apart from each other, or these devices can be integrated, or these devices can be arranged on different surfaces.

The display unit 151 may also include a touch sensor which senses a touch input received at the display unit. When a touch is input to the display unit 151, the touch sensor may be configured to sense this touch and the controller 180, for example, may generate a control command or other signal corresponding to the touch. The content which is input in the touching manner may be a text or numerical value, or a menu item which can be indicated or designated in various modes.

The touch sensor may be configured in a form of a film having a touch pattern, disposed between the window 151 a and a display on a rear surface of the window 151 a, or a metal wire which is patterned directly on the rear surface of the window 151 a. Alternatively, the touch sensor may be integrally formed with the display. For example, the touch sensor may be disposed on a substrate of the display or within the display.

The display unit 151 can also form a touch screen together with the touch sensor. Here, the touch screen can serve as the user input unit 123 (see FIG. 1A). Therefore, the touch screen can replace at least some of the functions of the first manipulation unit 123 a.

The first audio output module 152 a may be implemented in the form of a speaker to output voice audio, alarm sounds, multimedia audio reproduction, and the like. The window 151 a of the display unit 151 will typically include an aperture to permit audio generated by the first audio output module 152 a to pass. One alternative is to allow audio to be released along an assembly gap between the structural bodies (for example, a gap between the window 151 a and the front case 101). In this instance, a hole independently formed to output audio sounds can not be seen or is otherwise hidden in terms of appearance, thereby further simplifying the appearance and manufacturing of the mobile terminal 100.

The optical output module 154 can be configured to output light for indicating an event generation. Examples of such events include a message reception, a call signal reception, a missed call, an alarm, a schedule notice, an email reception, information reception through an application, and the like. When a user has checked a generated event, the controller can control the optical output unit 154 to stop the light output.

The first camera 121 a can process image frames such as still or moving images obtained by the image sensor in a capture mode or a video call mode. The processed image frames can then be displayed on the display unit 151 or stored in the memory 170. The first and second manipulation units 123 a and 123 b are examples of the user input unit 123, which can be manipulated by a user to provide input to the mobile terminal 100. The first and second manipulation units 123 a and 123 b may also be commonly referred to as a manipulating portion, and may employ any tactile method that allows the user to perform manipulation such as touch, push, scroll, or the like. The first and second manipulation units 123 a and 123 b can also employ any non-tactile method that allows the user to perform manipulation such as proximity touch, hovering, or the like.

FIG. 1B illustrates the first manipulation unit 123 a as a touch key, but possible alternatives include a mechanical key, a push key, a touch key, and combinations thereof. Input received at the first and second manipulation units 123 a and 123 b may be used in various ways. For example, the first manipulation unit 123 a may be used by the user to provide an input to a menu, home key, cancel, search, or the like, and the second manipulation unit 123 b may be used by the user to provide an input to control a volume level being output from the first or second audio output modules 152 a or 152 b, to switch to a touch recognition mode of the display unit 151, or the like.

As another example of the user input unit 123, a rear input unit can be located on the rear surface of the terminal body. The rear input unit can be manipulated by a user to provide input to the mobile terminal 100. The input can be used in a variety of different ways. For example, the rear input unit can be used by the user to provide an input for power on/off, start, end, scroll, control volume level being output from the first or second audio output modules 152 a or 152 b, switch to a touch recognition mode of the display unit 151, and the like. The rear input unit can be configured to permit touch input, a push input, or combinations thereof.

The rear input unit can be located to overlap the display unit 151 of the front side in a thickness direction of the terminal body. As one example, the rear input unit can be located on an upper end portion of the rear side of the terminal body such that a user can easily manipulate it using a forefinger when the user grabs the terminal body with one hand. Alternatively, the rear input unit can be positioned at most any location of the rear side of the terminal body.

Embodiments that include the rear input unit may implement some or all of the functionality of the first manipulation unit 123 a in the rear input unit. As such, in situations where the first manipulation unit 123 a is omitted from the front side, the display unit 151 can have a larger screen. As a further alternative, the mobile terminal 100 can include a finger scan sensor which scans a user's fingerprint. The controller 180 can then use fingerprint information sensed by the finger scan sensor as part of an authentication procedure. The finger scan sensor can also be installed in the display unit 151 or implemented in the user input unit 123.

The microphone 122 is shown located at an end of the mobile terminal 100, but other locations are possible. If desired, multiple microphones may be implemented, with such an arrangement permitting the receiving of stereo sounds.

The interface unit 160 serves as a path allowing the mobile terminal 100 to interface with external devices. For example, the interface unit 160 may include one or more of a connection terminal for connecting to another device (for example, an earphone, an external speaker, or the like), a port for near field communication (for example, an Infrared Data Association (IrDA) port, a Bluetooth port, a wireless LAN port, and the like), or a power supply terminal for supplying power to the mobile terminal 100. The interface unit 160 can be implemented in the form of a socket for accommodating an external card, such as Subscriber Identification Module (SIM), User Identity Module (UIM), or a memory card for information storage.

The second camera 121 b is shown located at the rear side of the terminal body and includes an image capturing direction that is substantially opposite to the image capturing direction of the first camera unit 121 a. If desired, the second camera 121 a can alternatively be located at other locations, or made to be moveable, in order to have a different image capturing direction from that which is shown.

The second camera 121 b can include a plurality of lenses arranged along at least one line. The plurality of lenses can also be arranged in a matrix configuration. The cameras may be referred to as an “array camera.” When the second camera 121 b is implemented as an array camera, images may be captured in various manners using the plurality of lenses and images with better qualities.

As shown in FIG. 1C, a flash 124 is shown adjacent to the second camera 121 b. When an image of a subject is captured with the camera 121 b, the flash 124 can illuminate the subject. As shown in FIG. 1C, the second audio output module 152 b can be located on the terminal body. The second audio output module 152 b can implement stereophonic sound functions in conjunction with the first audio output module 152 a, and can be also used for implementing a speaker phone mode for call communication.

At least one antenna for wireless communication can be located on the terminal body. The antenna may be installed in the terminal body or formed by the case. For example, an antenna which configures a part of the broadcast receiving module 111 can be retractable into the terminal body. Alternatively, an antenna can be formed using a film attached to an inner surface of the rear cover 103, or a case that includes a conductive material.

A power supply unit 190 for supplying power to the mobile terminal 100 may include a battery 191, which is mounted in the terminal body or detachably coupled to an outside of the terminal body. The battery 191 can receive power via a power source cable connected to the interface unit 160. Also, the battery 191 can be recharged in a wireless manner using a wireless charger. Wireless charging can be implemented by magnetic induction or electromagnetic resonance.

The rear cover 103 is shown coupled to the rear case 102 for shielding the battery 191, to prevent separation of the battery 191, and to protect the battery 191 from an external impact or from foreign material. When the battery 191 is detachable from the terminal body, the rear case 103 may be detachably coupled to the rear case 102.

An accessory for protecting an appearance or assisting or extending the functions of the mobile terminal 100 can also be provided on the mobile terminal 100. As one example of an accessory, a cover or pouch for covering or accommodating at least one surface of the mobile terminal 100 may be provided. The cover or pouch can cooperate with the display unit 151 to extend the function of the mobile terminal 100. Another example of the accessory is a touch pen for assisting or extending a touch input to a touch screen.

A communication system which is operable with the variously described mobile terminals will now be described in more detail. Such a communication system can be configured to utilize any of a variety of different air interfaces and/or physical layers. Examples of such air interfaces utilized by the communication system include Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), Universal Mobile Telecommunications System (UMTS) (including, Long Term Evolution (LTE), LTE-A (Long Term Evolution-Advanced)), Global System for Mobile Communications (GSM), and the like.

By way of a non-limiting example only, further description will relate to a CDMA communication system, but such teachings apply equally to other system types including a CDMA wireless communication system as well as OFDM (Orthogonal Frequency Division Multiplexing) wireless communication system. A CDMA wireless communication system generally includes one or more mobile terminals (MT or User Equipment, UE) 100, one or more base stations (BSs, NodeB, or evolved NodeB), one or more base station controllers (BSCs), and a mobile switching center (MSC). The MSC is configured to interface with a conventional Public Switched Telephone Network (PSTN) and the BSCs. The BSCs are coupled to the base stations via backhaul lines. The backhaul lines may be configured in accordance with any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, Frame Relay, HDSL, ADSL, or xDSL. Hence, the plurality of BSCs can be included in the CDMA wireless communication system.

Each base station may include one or more sectors, each sector having an omni-directional antenna or an antenna pointed in a particular direction radially away from the base station. Alternatively, each sector may include two or more different antennas. Each base station may be configured to support a plurality of frequency assignments, with each frequency assignment having a particular spectrum (e.g., 1.25 MHz, 5 MHz, etc.).

The intersection of sector and frequency assignment may be referred to as a CDMA channel. The base stations may also be referred to as Base Station Transceiver Subsystems (BTSs). In some cases, the term “base station” may be used to refer collectively to a BSC, and one or more base stations. The base stations may also be denoted as “cell sites.” Alternatively, individual sectors of a given base station may be referred to as cell sites.

A broadcasting transmitter (BT) transmits a broadcast signal to the mobile terminals 100 operating within the system. The broadcast receiving module 111 of FIG. 1A is typically configured inside the mobile terminal 100 to receive broadcast signals transmitted by the BT.

Global Positioning System (GPS) satellites for locating the position of the mobile terminal 100, for example, can cooperate with the CDMA wireless communication system. Useful position information can be obtained with greater or fewer satellites than two satellites. It is to be appreciated that other types of position detection technology, (i.e., location technology that can be used in addition to or instead of GPS location technology) can alternatively be implemented. If desired, at least one of the GPS satellites can alternatively or additionally be configured to provide satellite DMB transmissions.

The location information module 115 is generally configured to detect, calculate, or otherwise identify a position of the mobile terminal. As an example, the location information module 115 can include a Global Position System (GPS) module, a Wi-Fi module, or both. If desired, the location information module 115 may alternatively or additionally function with any of the other modules of the wireless communication unit 110 to obtain data related to the position of the mobile terminal.

A typical GPS module 115 can measure an accurate time and distance from three or more satellites, and accurately calculate a current location of the mobile terminal according to trigonometry based on the measured time and distances. A method of acquiring distance and time information from three satellites and performing error correction with a single satellite may be used. In particular, the GPS module may acquire an accurate time together with three-dimensional speed information as well as the location of the latitude, longitude and altitude values from the location information received from the satellites.

Furthermore, the GPS module can acquire speed information in real time to calculate a current position. Sometimes, accuracy of a measured position may be compromised when the mobile terminal is located in a blind spot of satellite signals, such as being located in an indoor space. In order to minimize the effect of such blind spots, an alternative or supplemental location technique, such as Wi-Fi Positioning System (WPS), may be utilized.

The Wi-Fi positioning system (WPS) refers to a location determination technology based on a wireless local area network (WLAN) using Wi-Fi as a technology for tracking the location of the mobile terminal 100. This technology typically includes the use of a Wi-Fi module in the mobile terminal 100 and a wireless access point for communicating with the Wi-Fi module. The Wi-Fi positioning system may include a Wi-Fi location determination server, a mobile terminal, a wireless access point (AP) connected to the mobile terminal, and a database stored with wireless AP information.

The mobile terminal connected to the wireless AP can transmit a location information request message to the Wi-Fi location determination server. The Wi-Fi location determination server extracts the information of the wireless AP connected to the mobile terminal 100, based on the location information request message (or signal) of the mobile terminal 100. The information of the wireless AP can be transmitted to the Wi-Fi location determination server through the mobile terminal 100, or can be transmitted to the Wi-Fi location determination server from the wireless AP.

The information of the wireless AP extracted based on the location information request message of the mobile terminal 100 may include one or more of media access control (MAC) address, service set identification (SSID), received signal strength indicator (RSSI), reference signal received Power (RSRP), reference signal received quality (RSRQ), channel information, privacy, network type, signal strength, noise strength, and the like.

The Wi-Fi location determination server can receive the information of the wireless AP connected to the mobile terminal 100 as described above, and can extract wireless AP information corresponding to the wireless AP connected to the mobile terminal from the pre-established database. The information of any wireless APs stored in the database may be information such as MAC address, SSID, RSSI, channel information, privacy, network type, latitude and longitude coordinate, building at which the wireless AP is located, floor number, detailed indoor location information (GPS coordinate available), AP owner's address, phone number, and the like. In order to remove wireless APs provided using a mobile AP or an illegal MAC address during a location determining process, the Wi-Fi location determination server can extract only a predetermined number of wireless AP information in order of high RSSI.

Then, the Wi-Fi location determination server can extract (analyze) location information of the mobile terminal 100 using at least one wireless AP information extracted from the database. A method for extracting (analyzing) location information of the mobile terminal 100 may include a Cell-ID method, a fingerprint method, a trigonometry method, a landmark method, and the like.

The Cell-ID method is used to determine a position of a wireless AP having the largest signal strength, among peripheral wireless AP information collected by a mobile terminal, as a position of the mobile terminal. The Cell-ID method is an implementation that is minimally complex, does not require additional costs, and location information can be rapidly acquired. However, in the Cell-ID method, the precision of positioning can fall below a desired threshold when the installation density of wireless APs is low.

The fingerprint method is used to collect signal strength information by selecting a reference position from a service area, and to track a position of a mobile terminal using the signal strength information transmitted from the mobile terminal based on the collected information. In order to use the fingerprint method, it is common for the characteristics of radio signals to be pre-stored in the form of a database.

The trigonometry method is used to calculate a position of a mobile terminal based on a distance between coordinates of at least three wireless APs and the mobile terminal. In order to measure the distance between the mobile terminal and the wireless APs, signal strength can be converted into distance information, Time of Arrival (ToA), Time Difference of Arrival (TDoA), Angle of Arrival (AoA), or the like may be taken for transmitted wireless signals.

The landmark method is used to measure a position of a mobile terminal using a known landmark transmitter. In addition to these position location methods, various algorithms can be used to extract (analyze) location information of a mobile terminal. Such extracted location information can be transmitted to the mobile terminal 100 through the Wi-Fi location determination server, thereby acquiring location information of the mobile terminal 100.

The mobile terminal 100 can acquire location information by being connected to at least one wireless AP. The number of wireless APs required to acquire location information of the mobile terminal 100 can be variously changed according to a wireless communication environment within which the mobile terminal 100 is positioned.

As previously described with regard to FIG. 1A, the mobile terminal can be configured to include short-range communication techniques such as Bluetooth™, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), UltraWideband (UWB), ZigBee, Near Field Communication (NFC), Wireless USB (Wireless Universal Serial Bus), and the like.

A typical NFC module provided at the mobile terminal supports short-range wireless communication, which is a non-contactable type of communication between mobile terminals and generally occurs within about 10 cm. The NFC module can operate in one of a card mode, a reader mode, or a P2P mode. The mobile terminal 100 may further include a security module for storing card information, in order to operate the NFC module in a card mode. The security module can be a physical medium such as Universal Integrated Circuit Card (UICC) (e.g., a Subscriber Identification Module (SIM) or Universal SIM (USIM)), a secure micro SD and a sticker, or a logical medium (e.g., embedded Secure Element (SE)) embedded in the mobile terminal. Single Wire Protocol (SWP)-based data exchange can be performed between the NFC module and the security module.

When the NFC module operates in a card mode, the mobile terminal can transmit card information on a general IC card to the outside. More specifically, if a mobile terminal having card information on a payment card (e.g, a credit card or a bus card) approaches a card reader, a short-range mobile payment can be executed. As another example, if a mobile terminal which stores card information on an entrance card approaches an entrance card reader, an entrance approval procedure can start. A card such as a credit card, a traffic card, or an entrance card may be included in the security module in the form of applet, and the security module may store card information on the card mounted therein. Card information for a payment card may include any of a card number, a remaining amount and usage history, and the like. Card information of an entrance card may include any of a user's name, a user's number (e.g., undergraduate number or staff number), an entrance history, and the like.

When the NFC module operates in a reader mode, the mobile terminal can read data from an external tag. The data received from the external tag by the mobile terminal can be coded into the NFC Data Exchange Format defined by the NFC Forum. The NFC Forum generally defines four record types. More specifically, the NFC Forum defines four Record Type Definitions (RTDs) such as smart poster, text, Uniform Resource Identifier (URI), and general control. If the data received from the external tag is a smart poster type, the controller can execute a browser (e.g., Internet browser). If the data received from the external tag is a text type, the controller can execute a text viewer. If the data received from the external tag is a URI type, the controller can execute a browser or originate a call. If the data received from the external tag is a general control type, the controller can execute a proper operation according to control content.

In some cases in which the NFC module operates in a P2P (Peer-to-Peer) mode, the mobile terminal can execute P2P communication with another mobile terminal. In this instance, Logical Link Control Protocol (LLCP) may be applied to the P2P communication. For P2P communication, connection may be generated between the mobile terminal and another mobile terminal. This connection may be categorized as a connectionless mode which ends after one packet is switched, and a connection-oriented mode in which packets are switched consecutively. For a typical P2P communication, data such as an electronic type name card, address information, a digital photo and a URL, a setup parameter for Bluetooth connection, Wi-Fi connection, etc. may be switched. The P2P mode can be effectively utilized in switching data of a small capacity, because an available distance for NFC communication is relatively short.

Further preferred embodiments will be described in more detail with reference to additional drawing figures. It is understood by those skilled in the art that the present features can be embodied in several forms without departing from the characteristics thereof. Hereinafter, an example of registering an icon of an application, which is being executed by a watch type mobile terminal, with a wallpaper of a connected mobile terminal according to an embodiment of the present invention will be described.

FIG. 2 is a ladder diagram illustrating an operation method between a mobile terminal and a watch type mobile terminal according to an embodiment of the present invention. Hereinafter, the watch type mobile terminal 200 is assumed to include the components of mobile terminal 100 shown in FIG. 1.

First, the mobile terminal 100 and the watch type mobile terminal 200 are connected to each other (S201). The mobile terminal 100 and the watch type mobile terminal 200 can be connected to each other through a short-range wireless communication protocol. Thus, each of the mobile terminal 100 and the watch type mobile terminal 200 may include a short-range communication module.

The watch type mobile terminal 200 displays an execution screen of an application which is being executed (S203). The watch type mobile terminal 200 can display the execution screen of the application in a state of being connected to the mobile terminal 100 through a short-range wireless communication protocol.

Further, the controller 180 of the mobile terminal 100 receives information on the application, which is being executed by the watch type mobile terminal 200, through the short-range communication module 114 (S205). For example, the watch type mobile terminal 200 can transmit information on the currently executed application to the mobile terminal 100 through the short-range communication module. The currently executed application can be displayed through the display unit of the watch type mobile terminal 200.

In addition, information on the application may include application identification information such as an application name, an application version, a content provider for providing the application or an application icon indicating the application. Further, if the watch type mobile terminal 200 is connected to the mobile terminal 100 and displays the execution screen of the application, the watch type mobile terminal can transmit the information on the application to the mobile terminal 100.

In addition, when receiving a message for requesting the information on the application from the mobile terminal 100, the watch type mobile terminal 200 can transmit the information on the executed application to the mobile terminal 100 in response to the request message. The controller 180 of the mobile terminal 100 checks whether the application is installed in the mobile terminal 100 based on the received information on the application (S207).

For example, the controller 180 can check whether the application being executed by the watch type mobile terminal 200 is installed, based on the application identification information such as the application name received from the watch type mobile terminal 200. If the application is installed in the mobile terminal 100 (Yes in S207), the controller 180 checks whether the version of the application installed in the mobile terminal 100 is equal to that of the application executed by the watch type mobile terminal 200 (S209).

Even when the application is installed in the mobile terminal 100, the execution screen of the application can be changed according to the version. The process of comparing the versions of the applications can also be omitted. That is, if the application is installed in the mobile terminal 100 in step S207, the process of step S211 can be immediately performed.

If the version of the application installed in the mobile terminal 100 is equal to that of the application executed by the watch type mobile terminal 200 (Yes in S209), the controller 180 displays the application icon corresponding to the application on the wallpaper of the mobile terminal 100 (S211). The controller 180 can register the application icon corresponding to the application having the same version as the application executed by the watch type mobile terminal 200 with the wallpaper.

In addition, the wallpaper may be a lock screen in a lock state when a lock function is set in the mobile terminal 100. In particular, the lock screen is displayed before entering a home screen of the mobile terminal 100 and operation of the mobile terminal 100 according to user input is restricted on the lock screen. That is, only an application according to selection of some icons or operation corresponding to input using a password or a passcode can be performed on the lock screen.

Further, the wallpaper can be an initial screen displayed before displaying the home screen of the mobile terminal 100 when the lock function is not set in the mobile terminal 100. For example, the initial screen may include time information indicating a current time and an application icon capable of rapidly executing an application.

The controller 180 can display the application icon of the application on the initial screen if the application executed by the watch type mobile terminal 200 is installed in the mobile terminal 100. Further, the controller 180 can output sound or vibration indicating that the application icon is automatically registered on the initial screen.

The controller 180 can also display a popup window indicating that the application icon is automatically registered with the wallpaper. Further, the controller 180 executes the application in response to selection of the displayed application icon and displays a detailed screen of the application through the display unit 151 (S213). The detailed screen of the application may include more information than the screen of the application displayed by the watch type mobile terminal 200.

The size of the display of the watch type mobile terminal 200 is generally less than that of the mobile terminal 100, such as a mobile phone. Therefore, a user can view only restricted information on the execution screen of the application displayed by the watch type mobile terminal 200.

According to the embodiment of the present invention, the user can view the execution screen of the application through a larger display than the watch type mobile terminal 200, thereby intuitively viewing more information. In addition, the controller 180 displays a screen for downloading the application (S215), when the application executed by the watch type mobile terminal 200 is not installed in the mobile terminal 100 (S207).

The screen for downloading the application can be an execution screen of an app store for downloading an application. In addition, if the application executed by the watch type mobile terminal 200 is installed in the mobile terminal 100 (S207) and the versions of the applications are different, the controller 180 displays a screen for downloading or updating an application (S215).

Further, the screen for updating the application can be an execution screen of an app store for updating the application to a latest version. The controller 180 downloads the application executed by the watch type mobile terminal 200 on a screen for downloading according to a request (S217). The controller 180 downloads the application and then performs the process of step S211. That is, the controller 180 can extract and register the application icon of the application with the wallpaper after downloading the application.

Hereinafter, steps S210 to S217 will be described with reference to FIGS. 3 to 8. In particular, FIGS. 3 to 8 are diagrams illustrating a process of registering an application icon of an application, which is being executed by a watch type mobile terminal, with a wallpaper of a mobile terminal according to an embodiment of the present invention.

First, referring to FIG. 3, the mobile terminal 100 and the watch type mobile terminal 200 can be connected to each other through the short-range wireless communication protocol. In addition, the watch type mobile terminal 200 can display the execution screen of the currently executed application through the display 251. For example, the execution screen of the application can be an execution screen of a navigation application. In contrast, the mobile terminal 100 displays a black screen 300 when power is not supplied or a reduced power is supplied to the display unit 151.

The mobile terminal 100 can receive information on the navigation application from the connected watch type mobile terminal 200. For example, the mobile terminal 100 can receive information on the navigation application currently executed by the watch type mobile terminal 200 upon being connected to the watch type mobile terminal 200. The mobile terminal 100 can also determine whether the navigation application is installed based on the received information on the navigation application.

Further, the mobile terminal 100 can display a navigation icon corresponding to the navigation application on the initial screen if the navigation application is installed. That is, the mobile terminal 100 can display a navigation icon 311, which was not displayed on the initial screen 310 of the mobile terminal 100, as shown in FIG. 4. If the navigation icon 311 is selected, the mobile terminal 100 can display a detailed screen 500 of the navigation application, as shown in FIG. 5.

As shown in FIGS. 3 and 4, the controller 180 can enter a power saving mode and display a power saving screen on the display 151 such as the black screen 300. In addition, the power saving mode uses less power than when displaying the home screen on the display 151. As shown in FIG. 4, the controller 180 displays the wallpaper on the display 151 in response to receiving the information on the application executed by the watch type mobile terminal. Further, the power saving screen includes a black screen when power to the display 151 is reduced compare to power being applied to the display 151 when the home screen is displayed as shown in FIG. 3. As shown in FIG. 4, the wallpaper includes a darkened screen with a clock and at least one unrestricted predetermined icon of the mobile terminal. Also, the navigation icon 311 is displayed with the least one unrestricted predetermined icon on the darkened screen as shown in FIG. 4.

The detailed screen 500 of the navigation application can include more information than the screen displayed through the display 251 of the watch type mobile terminal 200. That is, the detailed screen 500 of the navigation application can include detailed navigation information. Thus, the user can confirm navigation information through a larger screen.

If the navigation application is not installed in the mobile terminal 100, the mobile terminal 100 can display a popup window 610 for asking movement to the app store on the initial screen 310 while indicating that the navigation application is not installed, as shown in FIG. 6. As another example, even when the navigation application is installed in the mobile terminal 100, if the versions of the navigation applications are different, the mobile terminal 100 can display a popup window 620 for asking movement to the app store on the initial screen 310 while indicating that the navigation application needs to be updated, as shown in FIG. 7.

In FIGS. 6 and 7, when a confirm button 611 of the popup window is selected, the mobile terminal 100 can display a screen 800 for downloading or updating the navigation application, as shown in FIG. 8. According to another embodiment of the present invention, if the application executed by the watch type mobile terminal 200 is not installed or if the versions of the applications are different, the mobile terminal 100 can display a screen displayed by the watch type mobile terminal 200.

Next, FIGS. 9 and 10 are diagrams illustrating an example of displaying a screen displayed by the watch type mobile terminal if the application executed by the watch type mobile terminal is not installed or if the version of the applications are different. In particular, FIG. 9 is a ladder diagram illustrating an operation method between a mobile terminal and a watch type mobile terminal according to another embodiment of the present invention.

In FIG. 9, steps S901 to S913 are equal to step S201 to S213 described with reference to FIG. 2 and a repeated description thereof is omitted. The controller 180 of the mobile terminal 100 displays an execution screen being displayed by the watch type mobile terminal 200 if the application executed by the watch type mobile terminal 200 is not installed or if the versions of the applications are different (S915).

That is, the controller 180 can transmit a screen mirroring request to the watch type mobile terminal 200 if the application executed by the watch type mobile terminal 200 is not installed or if the versions of the applications are different. The screen mirroring request can be a request for transmitting information on the execution screen of the application displayed by the watch type mobile terminal 200.

The controller 180 can receive the information on the execution screen of the application displayed by the watch type mobile terminal 200 from the watch type mobile terminal 200 in response to the screen mirroring request. The controller 180 can display the execution screen 1000 based on the received information on the execution screen of the application, as shown in FIG. 10. The user can view the execution screen displayed through the watch type mobile terminal 200 on a larger screen, even when the application is not installed in the mobile terminal 100.
